, To all whom it may concern:

Be itiknown that I, HENRY A. TUTTLE,'1 citizen of the United States, residing at Taunton, in the county of Bristoland State ofMassachusetts, have invened an Improve- 7 meat in Actuating Mechanism for Reversing- Gearing, of which he following is a specilication. p In reverslnggearing, such for instance as shown in patent granted to me October 20,

1908, #901,664, a clutch and a brake are involved, the clutch operating to connect the pinion-carrier with one of the shaftswhereby the driven-shaft is rotated forward by and in the same direction as the drivingshaft, and the brake operating to engage the pinion-carrier and hold it at rest'whereby the driven-shaft is rotated backward by and in a direction opposite to the drivingshaft, and an actuating-lever is provided by I which the clutch and brake are operated. Said actuating-lever is pivotally supported, and is connected with both the clutch and the brake, and, upon movement ofit 1n opposite directions said clutch and brake are operated, respectively, but during its movement to operate either, theother is moved unnecessarily, which has been; found to be objectionable. Furthermore, said actuating lever requires considerable space in which to move, which is also objectionable.

This invention has for its object the provision of improved actuating-mechanism for the clutch and brake of reversing-gearing, whereby either is held at rest while the other is operatedg'and which occupies less space than the actuating-lever of the. patent aforesaid. i y

Figure l is a plan view of a revers ng gearing having a clutch anda brake, and

actuatingmechanism for the clutch and brake embodying this invention. Fig. 2Iis a side elevation of the same, Fig. 31s an enlarged vert cal section of the brake-mechanism. Fig. 4 is a plan view of the same.

Figs. 5 and 6 are details of the oscillatory actuating-means for the clutch and brake.

Fig. 7 is a detail of the clutch lever. I The improved actuatingmechanism is here shown in connection with the reversing gearing of the aforesaidpatent, yet it is adapted to other forms of reversing gear ing, involving the same general character istics. y i I I The reversing gearing here show-u comprises a driving-shaft a, and driven-shaft 6,

and intermediate gearing comprising. a spur-gear a secured to the drivingeshaft, pinions b engaging said spur-gear, an internal gear d secured] to the driven-shaft c,

and a pinion-carrier or case f bearing the pinions band which incloses the internal gear. The clutch here shown for connectprises a clutch-plate g, and anactuator therefor consisting of pivoted levers i, on said clutch-plate g havlng toes 2' which engage an abutment 72. on a fixed-ring h,

arranged on the hub of the internal-gear, and a sliding cone arranged on the drivenshaft 6 which engages the ends of the levers a", and a main clutch-lever j pivoted at j, which engagesthe sliding cone and is in the same direction as the driving-shaft.

Nor is the particular construction of the clutch material. 2 y m The brake here shownis similar in some respects to the brake of the aforesaid patent in that it comprises two semicircular members 0, o, for engagement with the pinion carrier f, said members having outwardly extended ends. Said members 0, 0, herein are attached together at oneof their ends by Patented Jan. 18, 1916.-

Applieation filed August 3, 1912. Serial No. 713,020. r i

'ing one of the shafts with the other 00111 a bolt, and said outwardly extended attached ends rest upon a stationary bar 20, which may be one of the supporting-bars for an.

engine. The opposite outwardly extended end 21ofthe lowermember 0, rests on top of a stationary bar 25, whichmay be another supporting-bar for the engine, and the similarly'formed'. end 22 of the upper 1118111 her 0, occupies a position above the end 21 of the lower inemberlsee Fig. 3). Said end 22 is movable toward and from the end 21, therebyto cause thetwo brake-members to engage the pinion-carrier, said members having sufficient resiliency to admit of such movement. Such movement of the upper member is herein accomplished by means of an actuator, here shown as a sliding-bar 30, and termed the brake-bar, which is provided with a forward extension 31, and an inclined portion 32, at the junction of said extension and the main portion of the bar. Theextension 31 is arranged between two rolls 35, 36. The roll 35 is arranged above the extension and is journaled in cars 37 rising from a base '38, set in a recess formedinthe under side of the end portion'21 of the lower brake member, said ears being extended up wardly, through a hole in the end of the up per brake-member. The roll 36 is arranged below the extension and is journaled in a bear ng 40, here shown as a plate, placed in a recess formed in the top of the end'of the upper brake member and adjustably supported in different elevated positions'by adjusting-screws. The journals of said roll occupy positions in verticalslots 41in the upright ears 37, and movement of said roll up and down is thu's'permitted. Normally,

the upper brake 'memberis disengaged from the pinion-carr er, as represented in F 1g. 3,

/ and the roll 36 occupies a position with its journals at "the upper ends "of the slots 41,

and the brake-bar occupies a position with "at forward part of its extension 31- etween .the rolls and 36. When the brake-bar 30 is thrust forward, in the direction of the arrow, Fig. 3-, its inclined portion engagesthe lower roll 36 and forces said roll and the end portion of-the, upper brake member downward, thereby to cause said member to frictionally engage the pinion-carrier. WVhen the brake bai 30 is 7 moved intlie opposite direction said upper brake-member will return to normal, as the pressure uponitis relieved. V

This particular form of brake isof advantage as itxadniits of the employment of a sliding brake-bar or actuator 30, yet so far as my invention is concerned, other forms of brakes may be employed; Said brake, how

. evei", structurally speaking, forms one of the features of this invention. e

To operate the brake the sliding brakebar '30 is moved longitudinally. The brake-bar30 is mounted to slide i bearings provided for it on the stationary bar 25, andhas, atone end, a downwardly extended pin 45, which enters asnail groove 46 in a disk 47, whichi's secured to an up right oscillatory shaft 48, supported by suit- 7 able bearings, and having'secured to it a V hand-wheel 49 for turning it. groove, ho-wever,as here shown,'comprises Said snail two semicircularv portions, arranged one in continuation of" the other, one of short di- Iameter, which is arranged concentric to the shaft 48, and the other of long diameter,

which is arranged concentric to the end of the former and extends nearly to the'edge of the disk. I

secured to said oscillatory shaft 48'.

Ilhe lower end of the pivoted clutch-lever is connected to a sliding bar having its hearings on the stationary bar 25, and said sliding bar has at one end a pin 51,

which is extended upwardly and enters a grooved disks 47 53, occupy the positions shown in-Fig, 5, wherein itpwill be seen that both pins 45, 51, occupy positions in their respective grooves intermediate the length thereof and near the center of the disks.

By turning the shaft 48 in a direction toward the right, Fig. 5, a half revolution,

the partsvwill then occupy the position shown in Fig. 1, wherein it will be seen that the pin 45 has followed in its groove along the semicircular portion of short diameter until it'has reached the end of the groove or thereabout, and, as said semicircular portion is concentric with the shaft 48 said pin 45 remains stationary during such: movement of the disk, and the pin 51 has followed in its groove along'the semicircular portion of long diameter until it has reached the end of'the groove or thereabout, and, as said semicircular portion extends nearly to the edge of the disk said pin 51 will bemoved in a direction radially to the axis of the shaft 48, and' thesliding bar 50 will be moved to in turn move the clutch-lever to --operatethe clutch to engage the pinion-carrier. By turning the shaft 48 in a direction toward the left, Fig. *5, ahalf revolution, the

" parts will then occupy the positions shown in Fig. 6, wherein. it will beseen that thepin 51 has followed in itsgroove along the semihasreached the end of the groove or there about and, as saidfsemicircular portion is concentric with the shaft 48 said pin151 remains stationary during such movement, and the pin 45 has followed in its groove along the semicircular portion of long diameter until it has reached the end of the groove or thereabout, and, as sai'd'semicircular portion extends nearly to the edge of the disk said pin 45 will be moved in a direction radially to the axis of the shaft48, and the brakebar 30 will be moved to in turn move the brake-member andcause the brake to engage the pinion-carrier. I

It'will thusbe' seen that as the shaft 48 is oscillated the clutch and the brake are separately and independently operated, the connections between the shaft "and the clutch circular portion of short diameter until it permitting movement of the shaft in one direction to operate the brake without mov-i being separateand independentof the other;
